Acute injury is caused by a rapid metabolic accumulation of bisulphite and sulphite. |
Wool may also be bleached by steeping in a fairly strong solution of bisulphite of soda and then washing well in water. |
Reductive agents such as gas sulphurous anhydride, liquid sulphurous anhydride, sulphurous acid, sulphite, bisulphite and hydrosulphite. |
The cyanide and bisulphite solution is then added with warming till the blue colour is destroyed. |
Used baths that are inactive but still contain products for coating, bisulphite, anodisers, phosphatisation, chroming, etc. |
Sulphurous acid may either be applied in the gaseous form or in solution as bisulphite of soda. |
